The aviation comprehensive test system can complete the data recording, analysis and storage of the equipment under test on the flight bus, combat bus and display bus to verify the consistency of the basic logic and input/output data of the equipment under test and the correctness of the processing cycle. The system has the characteristics of stability, versatility, scalability and strong reusability, which reduces the customer's personnel cost and time cost.
Function
The aviation comprehensive test system can complete the data recording, analysis and storage of the equipment under test on the flight bus, combat bus and combat bus to verify the consistency of the basic logic and input/output data of the equipment under test and the correctness of the processing cycle. The specific functions are as follows:
(1) Bus data acquisition function
It can collect all the data of the three buses in real time, and the data collection adopts a unified time scale to ensure the consistency of the data.
(2) Real-time analysis and processing of message blocks
It can automatically analyze and display the message blocks in the bus data in real time according to the definition of the bus ICD library.
(3) ICD library management function
By default, the ICD library is embedded in the program and the content cannot be viewed. Through the settings and password settings on the main interface, the content in the ICD library can be viewed.
(4) Real-time parameter display function
The parameters can be assigned to the parameter table according to the function to realize the centralized real-time display and recording of some important parameters, and the display form can be numbers or graphics.
(5)Bus recording function
All the collected bus information is recorded in the database in real time as the original data for later data analysis and processing or bus reconstruction.
(6) Data playback function
For the bus data recorded to the database, the data playback function can be used to analyze and process various data.
(7) Data analysis/evaluation function
The aviation comprehensive test system analyzes and evaluates the system functions of the equipment under test by extracting and analyzing the bus data, and giving the system acceptance test results.
The aviation comprehensive test system can call the algorithm model for verification, and the verification result can be compared with the theoretical data value of the corresponding model.
The aviation comprehensive test system can be verified by calling customized logic for different processes to verify the correctness of the process.
Each evaluation sub-module in the evaluation management software calculates the standard solution of the project according to the test items, test cases, system control commands and the information of each subsystem input by the tested equipment, and conducts the analysis with the information output from the tested equipment. Compare and give evaluation results. The evaluation results given include:
(a) Test the correctness of the function of the project;
(b) The system performance and compliance of the test items;
(c) The error between the output data of the device under test and the standard solution.
